The descriptor for this code is:

Engine Coolant Temperature Circuit Range / Performance problem

Anybody have any experience with this one? My temp gauge in the dash cluster hasn't ever acted strange, FWIW.

I've gotten this code 3 times since I bought the truck a year ago, and it would be nice to get it cleared for good.

According to the FSM you need to replace the coolant temp sensor. Not the one for the gauge on the dash, but the one for EFI

89422-35010 list $ 53.24


Oh, I've got one in stock ;)
